Input
Cross
point
The system clock inputs. All address and command lines are sampled on the cross point of the
rising edge of CK and falling edge of
rising edge of CK and falling edge of
. A Delay Locked Loop (DLL) circuit is driven from the
clock inputs and output timing for read operations is synchronized to the input clock.
CKE0, CKE1
Input
Active
High
Activates the DDR3 SDRAM CK signal when high and deactivates the CK signal when low. By
deactivating the clocks, CKE low initiates the Power Down mode or the Self Refresh mode.

Input
Active
Low
Enables the associated DDR3 SDRAM command decoder when low and disables the command
decoder when high. When the command decoder is disabled, new commands are ignored but
previous operations continue, Rank 0 is selected by
decoder when high. When the command decoder is disabled, new commands are ignored but
previous operations continue, Rank 0 is selected by

ODT0, ODT1
Input
Active
High
Asserts on-die termination for DQ, DM, DQS, and
signals if enabled via the DDR3 SDRAM
mode register.
DM0
– DM8
Input
Active
High
The data write masks, associated with one data byte. In Write mode, DM operates as a byte mask
by allowing input data to be written if it is low but blocks the write operation if it is high. In Read
mode, DM lines have no effect.

point
The data strobes, associated with one data byte, sourced with data transfers. In Write mode, the
data strobe is sourced by the controller and is centered in the data window. In Read mode, the
data strobe is sourced by the DDR3 SDRAM and is sent at the leading edge of the data window.

Input
-
During a Bank Activate command cycle, defines the row address when sampled at the cross point
of the rising edge of CK and falling edge of
of the rising edge of CK and falling edge of
. During a Read or Write command cycle, defines
the column address when sampled at the cross point of the rising edge of CK and falling edge of
. In addition to the column address, AP is used to invoke autoprecharge operation at the end of
the burst read or write cycle. If AP is high, autoprecharge is selected and BA0-BAn defines the
bank to be precharged. If AP is low, autoprecharge is disabled. During a Precharge command
cycle, AP is used in conjunction with BA0-BAn to control which bank(s) to precharge. If AP is
high, all banks will be precharged regardless of the state of BA0-BAn inputs. If AP is low, then
BA0-BAn are used to define which bank to precharge.
